Summary: MnZn ferrite homogeneous fibers were synthesized and used as reinforcing phase in MnZn ferrite materials. The doping of homogeneous fibers significantly affected the microstructure, magnetic, and mechanical properties of the materials. The addition of a certain content of homogeneous fibers resulted in more uniform and compact crystal structures, lower porosity, and fewer grain boundaries, leading to improved magnetic and mechanical properties. The best properties were obtained with a fiber content of about 2%.

Summary: This study investigated the intensified effects of metallic iron and graphite powders addition on the magnetic properties and impedance matching of cementitious composites containing MnZn ferrite. The addition of iron and graphite powders can improve the electromagnetic wave absorption of composites by enhancing magnetic loss and dielectric loss.

Summary: The magnetization reversal mechanisms in electrodeposited Co100-xFex (x = 0; 20; 30; 50) films were investigated. The films containing iron showed thinner thickness, lower texture, and smaller grain size, leading to larger coercivities. The angular dependence of coercivity exhibited a transition from domain wall depinning to inverse domain nucleation inside the grains.

Summary: The effective magnetic anisotropy field Heff of Fex Ni(100-x) (x = 15, 25, 38) nanowires within dense alumina templates of-35% porosity was determined using different methods including magnetization evolution, ferromagnetic resonance, and magnetization switching. The results showed variations in Heff values depending on the determination method, with the values from magnetization measurements being quite smaller than those from FMR measurements. It was suggested that new internal degrees of freedom need to be considered to describe the effective anisotropy in different processes.

Summary: A single-step electrochemical procedure for synthesizing a brush-like platform and studying its hysteresis properties and electrochemical response is described in this study. It is demonstrated that the direction of the magnetic easy axis of the brush-like architecture can be tailored, and the coercivity and remanence of the magnetic system can be controlled. The presence of an applied magnetic field enhances the electrode charge-transfer response of the Ni nanobrush, which is attributed to a larger electroactive area.

Summary: In this study, the catalytic performance of FePd nanowires with different compositions was investigated through functionalization and analysis of reaction rate constants. The results showed that Fe55Pd45 nanowires exhibited the highest catalytic activity, while Fe65Pd35 nanowires showed similar performance despite their lower Pd content. The presence of Fe atoms and the formation of an fcc phase in the alloy may contribute to the synergistic effect on catalytic activity.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
